-     @Deprecated
      public class IndyInterface
      extends Object

  Deprecated.
  Bytecode level interface for bootstrap methods used by invokedynamic. This class provides a logging ability by using the boolean system property groovy.indy.logging. Other than that this class contains the interfacing methods with bytecode for invokedynamic as well as some helper methods and classes.

        `callType` - - the type of the call
        `type` - - the call site type
        `name` - - the real method name
